Substituent effect on the assembly of coordination polymers containing isophthalic acid and its derivatives

Abstract

Four coordination polymers [Zn4(H2O)(ip)4(py)6]n1, {[Zn2(hip)2(py)4]2ยท(py)}n2, [Zn(tbip)(py)2]n3 and [Mn(tbip)(py)2]n4 (H2ip = isophthalic acid, H2hip = 5-hydroxyisophthalic acid, H2tbip = 5-tert-butylisophthalic acid, py = pyridine), have been hydrothermally synthesized and characterized. The photoluminescent properties of 1โ€“3 have also been investigated. For 1โ€“3, as substituents change from H, OH to tert-butyl, the coordination numbers of Zn2+ ions decrease, and the dimensionalities of the structures of 1โ€“3 decrease from 2D (4,4) net, 1D double stranded chain to 1D chain. For 3 and 4, as Mn2+ tends to have a higher coordination number as compared to Zn2+, the structure of 4 is a 2D (4,4) net while the structure of 3 is a 1D chain. The substituents on isophthalic acid influence the coordination environments of metal ions and the coordination modes of the carboxyls, and thus determine the structures of the coordination polymers. The coordination behavior of metal ions also affects the formation of the structures.
